there is a concept in psychotherapy - I believe it is called "optimal frustration".

At this state of frustration, the client is very upset and frustrated at the perceived witholding of soothing/emotion/caring from the therapist that they have to learn to develop self-soothing skills.

Children go through this stage as well and it is essential for normal individuation from the parent (or something like that). Yes, at first the emotion and the crying get stronger and louder, but the child will learn,

If, and I'm not saying she is, but if your therapist is withdrawing, then it would be a very natural, organic thing for her to do - and, in the long run, potentially essential in breaking your self-reported pattern.

This phase in therapy is obviously very hard for you, but hopefully you can see it through to its resolution. There could be a whole new world on the other side.
